Two marine aquariums have been installed at a Florida baseball park.
The two tanks at Miami Marlins' ballpark are located behind the home plate backstop, and are complete with fish, as this video shows.
The aquariums are made of fibreglass with acrylic panels which are more than 2.5cm/1" thick.
Marlin's first baseman Gaby Sanchez tested the strength of the aquariums by throwing a baseball at them. Club president David Samson said: "He threw a ball as hard as he could against the tank and it didn’t even make a mark and nothing moved inside the tank. We have an extra layer of glass in front of the glass that’s in front of the fish.
"No ball will (damage) the tank, as fast as Gaby threw it, that’s for sure."
But PETA has objected to the construction of the aquariums at the park, saying that the fish will be stressed by the bright lights, noise from the crowd and the reverberations of a baseball stadium.
